A Car Seat Fit for a King: A Look at Prince William and Kate Middleton's Choice of Carrier

When Prince William and wife Kate Middleton introduced the world to their third child, Prince Louis of Cambridge, they ushered him home in the Britax Römer Baby-Safe Infant Carrier.

The royal couple used the same brand of car seat to carry Prince George and Princess Charlotte home as well, which the company said is a testament to their quality.

"All three of them have been in the exact same car seat made by Britax," Kate Clark, the public relations and events manager for Britax, told InsideEdition.com. "I think they know that we are one of the safest brands out there. And, not only that, we're a British company."

Britax manufactures car seats and strollers. The company first reached out to Kate when she was pregnant with Prince George to give them the seat.

"They actually politely declined so on the day that he was born we were like, 'What brand are they going to come out with?' And lo and behold, they chose Britax!" Clark said. “So they chose it on their own! We didn’t offer it to them!"

And like most items associated with the royals, the brand has seen an increase in interest as a result of the apparent royal seal of approval.

"It’s really too soon to comment on direct sales related to the news, however, we’ve seen a lift in branded Google searches for Britax," the company said in a statement to InsideEdition.com, noting the spike was particularly high around the time Prince Louis made his royal debut. "We’re absolutely delighted to see that the Duke and Duchess of Cambridge have once again used a Britax infant car seat for their first ride home."

Children up to 35 pounds and 32 inches can safely fit in the carrier. The Britax Römer Baby-Safe Infant Carrier is not available in the U.S., but the company does manufacture a similar version for Americans, the Britax B-Safe Ultra.

"Super soft," Clark said. "[And] very, very safe."

But at the end of the day, parents— royal or not— should go with their gut in choosing the carrier best suited to hold their little prince or princess.

"All car seats are safe," Clark said. "The best car seat is the one that fits your car, fits your child and can be used correctly each and every time."
